The retrieval system of scientific and technological documents can make the disordered scientific and technological documents flow in an orderly way, facilitate the inquiry and retrieval of scientific and technological materials by scientific and technological workers, and greatly promote the exchange and dissemination of scientific and technological achievements. For some famous international retrieval institutions, such as SCI and EI. , which contains the core periodical information of all related disciplines, is updated quickly and can reflect the latest trends of international academic research in time. Based on these internationally renowned retrieval systems, we can not only query the latest scientific and technological literature (in the form of English abstracts), but also retrieve the citation of articles and reveal all the references in the original text. Based on this, we can obtain a batch of related documents of a certain subject, so once the papers are collected by these internationally renowned retrieval institutions, they can be quickly spread around the world and quoted by others, which is also a good publicity for the authors and their units, and can greatly improve their academic reputation and status. Therefore, the collection of this paper by internationally renowned retrieval institutions has attracted the attention of national scientific research and education management departments (such as Ministry of Science and Technology, Ministry of Education, the State Council Academic Degrees Committee and National Natural Science Foundation of China).
Because these internationally renowned retrieval institutions mainly collect English titles, abstracts, keywords, author information and references of papers of global core journals (EI page one database only contains titles, author information and information of original published journals). Therefore, whether the paper can be included by these internationally renowned retrieval institutions is particularly important in the following three aspects:
1, whether the journal published in the paper is the source journal of the retrieval institution (with a list of Chinese journals included in SCI and EI);
2. Whether the English abstract of the paper is standardized;
3. The composition of references and whether they are standardized.
Second, the standard writing of the abstract of the paper
1, abstract element
Concise and concrete abstract reflects the substantive content of the paper, shows enough information of the content of the paper, embodies the innovation of the paper and shows the important outline of the paper. Generally, it consists of four elements: specific research object, method, result and conclusion.
The object is the specific subject range involved in the research, development and investigation of the thesis, reflecting the research content, the main problems to be solved, the proposal of the problems, the establishment of the research direction and the positioning of the objectives.
Methods refer to principles, theories, conditions, materials, technologies, structures, equipment, means and procedures. In the process of studying the research object, it is a necessary means to complete the research object.
The result is the result, effect, performance, data, determined relationship, etc. It is obtained by the author's experiments with research methods and is the result of scientific research.
The conclusion is the author's analysis, research, comparison, evaluation, application and questions raised. It is a summary of achievements, showing the reliability, practicability and innovation of research results, reflecting the value and academic level of paper research, and is the window that determines paper retrieval.
2, abstract, keyword writing
To write an abstract, we must first correctly and comprehensively grasp the scope of the topic, carefully analyze the topic, and find out the specific object, specific methods, specific results and innovative conclusions drawn from the analysis results from the four elements of the abstract. Based on the above four elements, find out the topic concept words with high specificity in each part, and then organize these topic concept words which reflect the theme content correctly, and use logical related words to form a complete abstract. Then, with the theme of expressing the theme of the paper as the theme, with the key words as the tool, through patient scrutiny and simplification, we strive to make the abstract concise, logical and complete.
Of course, the four elements are important, but choosing the key words of the paper is the key to writing a good abstract, because the key words contain all the theme concepts of the paper, represent the main contents discussed in the literature, and are concise in purpose, method, result and conclusion. Keywords can be freely given according to the content of the paper, but they must be simple, common, clear in concept and highly specific (concrete), and try to avoid using uncommon and complicated words. Qualified abstracts are not only comprehensive in content, complete in elements, concise and to the point, but also try to incorporate simple, commonly used, clear in concept and highly specific keywords.
3. Writing requirements of abstract
Based on the requirements of famous retrieval systems at home and abroad for abstract writing and the specifications for abstract writing formulated by peer journals, general Chinese abstract writing should meet the following requirements:
① The abstract is based on the principle of not omitting the theme concept, with 200~300 words in Chinese and 100 ~ 150 words in English;
(2) The first sentence of the abstract should not be repeated with the title of the paper, and each abstract is arranged side by side with the title, which is the first sentence of the abstract;
③ Starting with important facts, highlight the new information of the paper, namely, new topics, new methods, innovative conclusions and achievements.
The narrative should be complete, clear, concise, logical and complete in structure. The background and past research information should be deleted, not including the author's future plans, to prevent literary decoration and useless narration;
⑤ If other people's work or research results are involved in the abstract, try to list their names;
⑥ Statements such as "number ××××", "equation ×××××" and "reference ×××××" cannot appear in the abstract, and special characters and mathematical expressions composed of special characters are not used, and words can be used for expression and narration when necessary;
The spelling of words can be spelled in English and American, but it must be consistent in every article;
⑧ Write in the third person, continuously, without dividing paragraphs;
Don't start with a number, Chinese and English must correspond.

Title: Research on the Core Competitiveness of Resource-based Enterprises —— Taking Coal Enterprises as an Example
Energy is an important foundation of the national economy and an indispensable basic condition for the normal operation of modern society. Coal is the main energy source in China and plays a strategic role in the development of national economy. Coal enterprise is an important micro-subject of energy activities, which has experienced many years of planned economy and market economy. With the global economic integration and the deepening of China's reform and opening up, it is an important mission for our coal workers and theoretical workers to build the core competitiveness of coal enterprises and obtain and maintain sustainable competitive advantages. Taking coal enterprises as an example, guided by economics, enterprise core competitiveness theory and knowledge economy theory, this paper puts forward the identification standard of coal enterprises' core competitiveness through the regular analysis of their operating characteristics, and then puts forward the basic path to cultivate and enhance the core competitiveness of coal enterprises, so as to guide China's coal enterprises to become stronger and bigger according to their own laws, improve their overall competitive strength and realize sustainable development under the domestic and international background, based on China's actual national conditions. It also provides a path analysis for China to implement the strategy of energy resources security and economic security, establish an effective strategic model, and enhance the core competitiveness of energy enterprises going global.
Keywords: coal enterprises; Core competitiveness; energy security
Thirdly, the composition and description requirements of references in the paper.
All published books, papers, specifications and patents. Can be used as a reference. References are closely related to the preface (introduction) of the paper. Modern scientific and technological research work is carried out on the basis of predecessors' work. When scientific and technological workers carry out a scientific research work, the most basic work is literature retrieval. Through the retrieval work, they can know what research work others have done in this field, and then understand the progress and progress of others' work, as well as others'.
Therefore, when writing a paper, we should summarize the work of others in the preface, point out the connection and difference between the work of others and the work of this paper, and what progress this paper hopes to make. When quoting other people's works, we must give references to make them reasonable, so the references after the text can reflect the author's possession of information from one side, and then reflect the academic level of this paper. If the references behind the paper are all textbooks and books published long ago in China, it means that the author has some very old documents and the author's knowledge is outdated, so it is difficult for the paper to have a high academic level; If the references after the paper are all the latest achievements in this field found by the author through internationally renowned retrieval institutions, it means that the author has a large number of the latest documents and his research work is at the latest frontier in this field, and the chances of the paper being included by internationally renowned retrieval institutions will greatly increase. Therefore, it is suggested that the author make full use of internationally renowned retrieval institutions to query the papers published in some famous core journals at home and abroad as reference documents.
